T aZZ whom it may concern.-

Be it known that I, HEXRY E. TABER, of Vatkins, in the county of Schuyler, in the State of New York, have invented new and useful Improvements in Stoves or Furnaces, of which the following, taken in connection with the accompanying drawings, is a full,

clear, and exact description.

This invention consists in a novel combina tion, with a stove or furnace, of air-ducts extending through the same, so as to become heated thereby and serve to greatly augment the heating capacity of said stove or furnace, and at the same time ventilate the apartment containing the same, all as hereinafter more fully described, and specifically set forth in the claims.

In the annexed drawings, Figurel is a vertical section of a stove embodying my invention. Fig. 2 is a detached top plan view of the air-ducts, which are arranged across the stove above the fire-pot. Fig. 3 is a horizontal transverse section of said ducts; and Fig. at is avertical transverse section of the same on line :0 m, Fig. 3.

Similar letters of reference indicate corre sponding parts.

A represents a magazine-stove of any usual and well-known style and construction. B denotes the fire-pot, and D the ash-pit arranged for a downdraft at their exterior.

M represents the magazine, and O the cover thereof, provided with a solid base having a central opening, 0, which cover I provide with perforations or ports i '1'. Above the firepot B, and preferably between the same and lower end of the magazine, I arrange horizontally across the interior of the stove two semicircular air-ducts, a a, which are united by a diametrical duct, (4', as shown in Fig. 3 of the drawings. Said diametrical duct communicates at opposite ends with only one end of each of the ducts a a, soas to form a tortuous passage. To two diametrieal opposite points in the semicircular ducts a a are connected two ducts, b Z), which extend vertically down through the bottom of the stove at the outer side of the fire-pot and ash-pit, as shown in Fig. 1 of the drawings. A duct, b, extending across the under side of the stove, connects the ducts b I) at their lower end. Another duct, b, is we tended from the duct 1) to the exterior of the building to admit fresh air to the beforedcscribed ducts. At the junction of the ducts b and b the latter is provided with a port, 6, and across this port is arranged a valve, r, which can be turned so as to open and close either the port 6 or the passage through the duct 1).

c 0 represent two ducts which extend from the semicircular ducts a (L up through the top of the stove at the outside of the magazine M, and d is a duct extending from the diametrical duct to up into the magazine, and thus communicates by means of the opening 0 with the perforations in the cover 0. From the duct (1 projects laterally through the side of the magazine a duct, (1, by means of which the duct (1 communicates with the combustionch'ainber surrounding the magazine. A valve, f, is arranged across the junction of the two pipes (Z and (1, so as to permit of opening and closing either the passage through the duct (6 to the upper part of the magazine or the pas sage from the duct (1 to the duct (1'.

It is obvious that the described air-ducts can be connected in a similar manner to a furnacc of most any ordinary construction, and I therefore do not limit myself to the application of said ducts to the stove hercinbefore described.

The operation of my invention is as follows: \Vhen it is desired to increase the ventilation of the apartment in which the stove or furnace is located, I turn the valve 0 so as to open the port 6. This allows the air to pass from the aforesaid apartment through the port 0, thence through the ducts I) and b b, and into the semicircular ducts a a, the two currents ofair meeting at the center ofthe diametrical duct (1., from whence they ascend into the d not (I, and by closing the valve f the air, which has become thoroughly and intensely heated in its passage through the ducts b b, a a, and a, is allowed to escape through the ports t i of the cover 0, and thus pass int-o the apartment aforesaid. \Vhen it is desired to utilize the aforesaid heated air for promoting combustion in the combustion-chamber, I turn the valve f so as to open communication between the ducts d and d, and thus allow the heated air to pass through the duct (1' into the combustiouchamber.

The duct 0 c, forming constant passages of hot air from the semicircular ducts a a through the top of the stove, are made considerably smaller than the duct d, so as to partly choke the passages through the ducts c a and permit of the passage of the hot air through the duct 11.

It will be observed that by the arrangement of the air-ducts in the stove or furnace in the manner herein described and shown I am enabled to draw the foul and cold air from the bottom of the room containing the stove or furnace and thoroughly and intensely heat said air without detracting from the ordinary heating capacity of the stove'or furnace, and by the discharge of said heated air from the ducts into the apartment I derive a greater amount of heat from less consumption of fuel.

Having described myinvention, whatlclainn as new, and desire to secure by Letters Patent, 1s r 1. In combination with a stove or furnace,

, an air-heater located within the stove,and consisting of semicircular ducts connected at opposite ends by a diametrical duct, and of vertical ducts leading, respectively, through the base of the stove to the free ends of the semicircular ducts and from the diametrical duct through the top of the stove, substantially as specified.

2. In combination with a stove or furnace, an air-heaterlocated within the stove,and consisting of semicircular ducts connected at opposite ends by a diametrical duct, and of vertical ducts leading, respectively, through the base and top of the stove to the semicircular ducts, substantially as specified.

3. In combination with a stove or furnace. an air -heater located within the stove, and consisting of semicircular ducts connected at opposite ends by a diametrical duct, the ducts b b, tapping the semicircular ducts, respectively, at diametrically-opposite points and extending through the bottom, and the ducts c 0, extending from said semicircular ducts through the top of the stove, said ducts b b and c 0 having their exit outside of the magazine, substantially as specified 4. In a magazine stove or furnace, the combination, with a hot-air duct located above the fire-pot, of an air-inlet duct having a port outside of the stove or furnace and provided with a valve, one or more air-ducts leading from said inlet-duct and communicating with the hot-air duct, an air-ductleading from said hot-air duct and communicating with the chamber formed by the cover, the perforated cover, and an air-duct leading from the lastmentioned duct to the cornbustion-chamber, and provided with a valve, whereby, when air is admitted to the inlet-duct and heated on its passage through the hot'air ducts, it can be discharged either into the apartment in which is located the stove or into the combustion-chamber and thence to the smoke-flue, substantially as specified.

5. In a magazine stove or furnace, the 00111- bination,with the semicircular air-ducts, each having one end thereof connected together by a diametrical air-duct, of an inlet air-duct having a, portprovided with a valve, airducts leading from said inlet-duct and communicating with the semicircular ducts, an

air-duct leading from the diametrical duct and communicating with the chamber formed bythe cover, the perforated cover, and an airduct connecting the last-mentioned duct with the combustion-chamber,and provided with a connecting with chamber G, substantially as shown and described.

7. In a magazine stove or furnace, the perforated cover 0, the semicircular ducts a a, arranged horizontally between the magazine and fire-pot and united by the diametrical duct a, the ducts b I), tapping the semicircular ducts, respectively, at diametrically-opposite points and extending through the bottom of the stove or furnace, the ducts c 0, extending from the semicircular ducts through the top of said stove or furnace outside of the magazine, and the duct d, extending from the diametrical duct through the magazine, all combined to operate substantially as described.

8. In a magazine-stove, the combination of the semicircular ducts a a, arranged horizontally between the magazine and fire-pot and united by the diametrical duct a, the ducts b b, tapping the semicircular ducts, respectively,

at diametrically-opposite points and extending through the bottom of the stove, at the outside of the fire-pot, the duct b, connecting the ducts b b at the under side of the stove, the duct 11, extending outward from the duct 12, the port 6 at the juncture of the ducts b b, the valve 22 across said port, the ducts c 0, extending from the semicircular ducts through the top of the stove outside of the magazine, the duct d, extending from the diametrical duct through the magazine, the duct d, extending from duct (1 laterally through the magazine, the valve f, and the magazine-cover 0, provided with perforations 2' 13, substantially as described and shown.

In testimony whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Watkins, in the county of Schuyler, in the State of New York, this 1st day of January, 1886.
